摘要:
The present disclosure provides toners and processes for making said toners. In embodiments, the toners are invisible when viewed under natural light, but possess a UV additive that renders them visible when exposed to UV light of a specific wavelength. By selecting the appropriate UV additive and ionic crosslinker, with optional chelating agent, the gloss of the toner may be tailored to match the gloss of any substrate, such as paper, to which the toner is to be applied, thereby further enhancing its invisibility under visible light.
摘要:
The present disclosure provides white toner compositions and processes for making same. In embodiments, a desirable white toner may be produced without having to resort to excessive pigment loading, having desirable gloss characteristics.

摘要:
A pigment particle coated with at least one of a resin and a charge control surface additive, wherein the pigment particle is a pearlescent or metallic pigment. The pigment adds pearlescent effects and is of a size and charge as to be used as a toner material in electrostatographic or xerographic image formation.
摘要:
A process for making a self-emulsifying composite suitable for use in forming latex emulsions includes contacting a resin with a solid or highly concentrated surfactant, a solid neutralizing agent in the absence of water and an organic solvent to form a mixture, melt mixing the mixture, and forming a self-emulsifying composite of the melt mixed mixture such as a granule. Self-emulsifying granules are also provided and configured to form a latex emulsion when added to water, which may then be utilized to form a toner.

摘要:
A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one amorphous polyester resin with a viscosity reducing additive in the absence of an organic solvent to form a resin mixture either via an extruder or batch process, and adding a surfactant, neutralizing agent, and deionized water to the resin mixture.
摘要:
A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one polyester resin with a bio-based solvent to form a resin mixture, adding a neutralizing agent and deionized water to the resin mixture, removing the solvent from the formed latex, and recovering the emulsion. The solvent removed from the formed latex may be re-used, making the process very environmentally friendly.
摘要:
Various solvent-assisted extrusion processes are disclosed that are suitable for forming high yield, low coarse content, polyester latexes that may be utilized in forming a toner.
